Use the following information to answer the next three exercises,61, 62, &63.

Suppose a group is interested in determining whether teenagers obtain their drivers licenses at approximately the same average age across the country. Suppose that the following data are randomly collected from five teenagers in each region of the country. The numbers represent the age at which teenagers obtained their drivers licenses. Take .05

	Northeast	South	West	Central	East
	16.3	16.9	16.4	16.2	17.1
	16.1	16.5	16.5	16.6	17.2
	16.4	16.4	16.6	16.5	16.6
	16.5	16.2	16.1	16.4	16.8

#67:Table 13.23lists the number of pages in four different types of magazines.

Home Decorating	News	Health	Computer
172	87	82	104
286	94	153	136
163	123	87	98
205	106	103	207
197	101	96	146

Using a significance level of 5%, test the hypothesis that the four magazine types have the same mean length. Give the following:

1. Null and Alternative Hypotheses.

2.df(n) = ______ df(d) = _______

3. F-statistic = __________

4. P-value = ___________

5. F-critical = __________

6. Decision: ___________

7. Conclusion: __________
